  Abstract

The high mortality and morbidity of patients in terminal heart failure are a therapeutic challenge to modern medicine. Surgically, cardiac transplantation is an excellent treatment for many patients. However, lack of donors combined with an increasing number of patients has led to the search for other surgical strategies. Patients with symptomatic large left ventricular aneurysms have been treated with resection of the aneurysm and closure of the left ventricle either directly (linear closure, first reported by Cooley) or by implantation of a patch (endoventricular patch plasty or Dor procedure). Akinetic areas of the left ventricle have also been successfully treated by the latter method. According to the law of Laplace, large dilated ventricles have increased wall tension and thus increased oxygen consumption. Based on this fact, Batista and coworkers have reduced the volume of enlarged left ventricles in patients in terminal heart failure by removing a wedge of myocardium from the apex of the heart towards the base of the left ventricular free wall. Although a favorable outcome has been reported in selected patients, this method is currently not recommended for treatment of heart failure because of high surgical failure rates.

The present paper reviews some of the relevant literature regarding surgical left ventricular remodeling in heart failure. Two new techniques (Myosplint and CorCap cardiac support device) are also briefly described.

Key Words: Left ventricular aneurysm • Dor procedure • Batista procedure • Endoventricular patch plasty • Surgical left ventricular remodeling
